Be aware that with robocopy, the /MIR switch will delete a file in the

Ah yes, very good point. But I am using that deliberately in some of my
cases where I might change file names to help manage data structures
better. It does mean you are not left with multiple copies of otherwise
very similar stuff, much of it slightly out of date.

I always wonder why so few seem to recommend Microsoft's Synctoy to
provide the various types of data backup as discussed above. Is there a
reason?

Other stuff works better.
